MemorySwapMeter: align with CPU meter

Use the same width for each sub meter to align with CPU meter.
Currently if the total width is even, so it does not split exactly into
2 equal parts plus 1 (for the middle space character column), the extra
column is added to the second meter width.

Closes: #783
